Smart certification: protecting the originality of the product in the eyewear sector
No full textThe growing diffusion of the technologies related to the Internet of Things (IoT) paradigm not only facilitates the connectivity among a huge amount of different devices, but also the variety of applications and services which can be provided to users. Everyday objects, equipped with the technologies involved in such a paradigm, become smart and are able to guarantee users who own them to be connected “always, in any place, at any time and with any object”. Consequently, the opportunity of communicating in real time enables the design and development of novel customizable functionalities, which are even closer to the needs of the users. Different application domains can benefit from this innovation, including the ophthalmology and eyewear sector. In such a context, the lenses and the eyeglasses frames become smart, thanks to the adoption of IoT paradigm. A relevant application in such an area concerns the definition of a system able to guarantee the originality of the product (and, so, verify the certification), as well as preventing the spread of imitations and counterfeit products, recognizing them in real time. In this paper, a preliminary approach for solving such emerged issues is proposed. More in detail, the main requirements and involved functionalities are pointed out and represented in a coherent flow, through Node-RED, which is a flow-based programming tool targeted to support the design and development of IoT applications
How to evaluate an Internet of Things system: models, case studies, and real developments
No full textThe paper proposes the use of Node-RED, a flow-based programming tool targeted to Internet of Things (IoT), along with a series of case studies related to different IoT contexts, which demonstrate Node-RED’s potentialities and outcomings towards the realization of well-structured IoT environments. The analyzed applications potentially include a wide range of domains, ranging from smart cities, smart buildings, smart homes/offices, smart retailing, to smart transportation, smart logistics, smart agriculture, smart health, military scenarios, and so on. The motivations behind the presented work are related to the fact that IoT application fields usually involve the same technologies and communication protocols, which are frequently adopted for totally different purposes. Issues such as systems’ interoperabiliy, scalability, security and privacy naturally emerge, due to the huge amount of heterogeneous devices acting in the IoT environment itself and to the wireless nature of information transmissions. As a consequence, it is fundamental to dispose of adequate tools for supporting developers in design the network architecture and messages’ exchange, in order to realize efficient and effective IoT network infrastructures

Privacy Aware Systems
No full textEnterprises have adopted various strategies to protect customers’ privacy and to make public their policies. This chapter presents a conceptual model for supporting the definition of privacy policies. The model, described by means of UML, introduces a set of concepts concerning privacy and defines the existent relationships among those concepts along with the interfaces for the definition of privacy related mechanisms. The chapter also illustrates how the conceptual model can be used to build design solutions for three recurrent requirements for privacy aware systems concerning the definition of anonymity, the acquisition of the informed consent, and privacy policies enforcement. The proposed problems are separately illustrated and a solution based on the conceptual model is described for each of them. Finally, in order to assess the model and the design solutions, this chapter presents an example concerning the health domain.</jats:p
Attribute-based policies through microservices in a smart home scenario
Get PDFApplication containerization allows for efficient resource utilization and improved performance when compared to traditional virtualization techniques. However, managing multiple containers and providing services such as load balancing, fault tolerance and security represent challenging tasks in the emerging microservices architectures. In this context, Kubernetes platform allows to build resilient distributed containers. Besides its efficiency in terms of configuration and architectural resiliency, it must also guarantee the access control to the managed resources. In fact, information must be protected throughout the different microservices which compose an application. To cope with such an issue, this paper proposes the definition of attribute-based policies able to regulate data disclosure within a Kubernetes-based microservices network. Simulations are carried out in a local Minikube environment, considering a smart residence scenario. The investigated metrics include response time, required memory, CPU load, and disk usage
5G in the Internet of Things era: an overview on security and privacy challenges
No full textNow reaching 2020, the world is witnessing the initial diffusion of 5G networks, which promise to revolutionize the mobile wireless communications, providing faster services, very low delays, and a very pervasive connectivity via mobile devices. It is worth to remark that the main paradigm which will take advantage from 5G is really the Internet of Things (IoT). However, the spreading of 5G technology also generates important concerns in terms of security and privacy, due to the continuous and wireless connection to the network, which hinders the reliability of the involved devices. This paper deeply analyzed the current state of the art about the existing security and privacy solutions tailored to 5G. More in detail, the following requirements are discussed: data integrity, confidentiality, authentication, access control, non-repudiation, trust, privacy, identity management, key management, policy enforcement, and intrusion detection. Furthermore, the paper aims to shed the light on future research directions towards the realization of secure and privacy aware 5G systems. To this end, the role of emerging paradigms, such as IoT, fog computing, and blockchain is investigated
